Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN In 1959 The 3 R's were introduced by W.M.S. Russell and R.L. Burch in their book The Principles of Humane Experimental Technique. The 3 R's are replacement, reduction, and refinement of the use of animals in research. The use of cell lines and tissue cultures that originated from research animals is a replacement technique, as it allows for many experiments to be conducted in vitro. Harvesting...

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease. Cleaning The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Methods of Sterilization II: Chemical Methods

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements. Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Methods of Sterilization I: Physical Methods

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation. Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

In this video, we demonstrate the dissection of the cornea-bearing anterior segment of the porcine eye. The isolated segment can be used for organ culturing to study the pathophysiology of eye disorders.
FAQs
The sterile tip acts as a barrier between the liquid and potential sources of microorganisms during transfer. Its value depends not only on initial sterility but also on maintaining that condition while dispensing. Preventing contact with the eye or nearby surfaces helps keep the delivered solution and its intended biological target uncontaminated.
Controlled dispensing supports more consistent delivery from one application to the next. In ocular treatment, that consistency helps align the amount of solution with the intended use. In biology experiments, it can reduce variation when a solution is applied to a specimen or living tissue, making handling more reproducible without adding unnecessary liquid.
Contact with the eye or surrounding surfaces creates a route by which microorganisms or other contaminants can reach the tip and then the solution. Once sterility is compromised, later applications may no longer represent the intended clean treatment or experimental condition. Avoiding contact therefore protects both the user and the reliability of biological work.
Use begins by preserving the dropper's sterile condition, followed by dispensing the required small volume without touching the eye or nearby surfaces. Throughout use, careful handling remains important because contact can introduce microorganisms. This approach supports safer ocular delivery and cleaner work when the dropper is used with sensitive biological material.
The device can support ocular treatments, specimen handling, and controlled application of solutions to living tissues. These settings differ in purpose, but all require a small amount of liquid to reach a specific biological target. Using a sterile dropper helps protect sensitive samples and limits contamination that could alter observations or outcomes.
In patient-facing use, preserving sterility helps reduce the risk that microorganisms will be introduced during solution delivery. In research, contamination can affect sensitive samples and experimental results, making observations harder to interpret. The same handling principle therefore supports patient safety in ocular treatment and improves confidence in biological procedures.
